2011-01-04Mouse pointer integration. Jeff Brown
Added support for loading the pointer icon from a resource. Moved the system server related bits of the input manager out of libui and into libinput since they do not need to be linked into applications. Change-Id: Iec11e0725b3add2b905c51f8ea2c3b4b0d1a2d67
2010-09-12Input dispatcher ANR handling enhancements. Jeff Brown
This change is essentially a rewrite of the main input dispatcher loop with the target identification folded in. Since the input dispatcher now has all of the window state, it can make better decisions about when to ANR. Added a .5 second deadline for processing app switch keys. This behavior predates Gingerbread but had not previously been ported. Fixed some timing inaccuracies in the ANR accounting that could cause applications to ANR sooner than they should have. Added a mechanism for tracking key and motion events that have been dispatched to a window so that appropriate cancelation events can be synthesized when recovering from ANR. This change helps to keep applications in sync so they don't end up with stuck buttons upon recovery from ANRs. Added more comments to describe the tricky parts of PollLoop.

2010-07-29DO NOT MERGE: Fix input event injection ANRs on UI thread. Jeff Brown
Added a new asynchronous injection mode and made the existing synchronization mechanism more robust. Change-Id: Ia4aa04fd9b75ea2461a844c5b7933c831c1027e6
2010-07-28Refactor input reader to support new device types more easily. Jeff Brown
Refactored the input reader so that each raw input protocol is handled by a separate subclass of the new InputMapper type. This way, behaviors pertaining to keyboard, trackballs, touchscreens, switches and other devices are clearly distinguished for improved maintainability. Added partial support for describing capabilities of input devices (incomplete and untested for now, will be fleshed out in later commits). Simplified EventHub interface somewhat since InputReader is taking over more of the work. Cleaned up some of the interactions between InputManager and WindowManagerService related to reading input state. Fixed swiping finger from screen edge into display area. Added logging of device information to 'dumpsys window'. Change-Id: I17faffc33e3aec3a0f33f0b37e81a70609378612
2010-06-28Native input event dispatching. Jeff Brown
Target identification is now fully native. Fixed a couple of minor issues related to input injection. Native input enabled by default, can be disabled by setting WindowManagerPolicy.ENABLE_NATIVE_INPUT_DISPATCH to false. Change-Id: I7edf66ed3e987cc9306ad4743ac57a116af452ff
2010-06-21More native input event dispatching. Jeff Brown
Added ANRs handling. Added event injection. Fixed a NPE ActivityManagerServer writing ANRs to the drop box. Fixed HOME key interception. Fixed trackball reporting. Fixed pointer rotation in landscape mode. Change-Id: I50340f559f22899ab924e220a78119ffc79469b7
2010-06-15More work in progress on native events. Jeff Brown
Refactored the code to eliminate potential deadlocks due to re-entrant calls from the policy into the dispatcher. Also added some plumbing that will be used to notify the framework about ANRs. Change-Id: Iba7a10de0cb3c56cd7520d6ce716db52fdcc94ff
2010-06-13Native input dispatch rewrite work in progress. Jeff Brown
The old dispatch mechanism has been left in place and continues to be used by default for now. To enable native input dispatch, edit the ENABLE_NATIVE_DISPATCH constant in WindowManagerPolicy. Includes part of the new input event NDK API. Some details TBD. To wire up input dispatch, as the ViewRoot adds a window to the window session it receives an InputChannel object as an output argument. The InputChannel encapsulates the file descriptors for a shared memory region and two pipe end-points. The ViewRoot then provides the InputChannel to the InputQueue. Behind the scenes, InputQueue simply attaches handlers to the native PollLoop object that underlies the MessageQueue. This way MessageQueue doesn't need to know anything about input dispatch per-se, it just exposes (in native code) a PollLoop that other components can use to monitor file descriptor state changes. There can be zero or more targets for any given input event. Each input target is specified by its input channel and some parameters including flags, an X/Y coordinate offset, and the dispatch timeout. An input target can request either synchronous dispatch (for foreground apps) or asynchronous dispatch (fire-and-forget for wallpapers and "outside" targets). Currently, finding the appropriate input targets for an event requires a call back into the WindowManagerServer from native code. In the future this will be refactored to avoid most of these callbacks except as required to handle pending focus transitions. End-to-end event dispatch mostly works! To do: event injection, rate limiting, ANRs, testing, optimization, etc. Change-Id: I8c36b2b9e0a2d27392040ecda0f51b636456de25
